30% of congressional incumbents not seeking re-election this year have endorsed a successor

On Feb. 9, U.S. Rep. Jerrold Nadler (D-N.Y.), who is not seeking re-election this year, endorsed Micah Lasher (D) in the Democratic primary election to succeed him in representing New York's 12th Congressional District.

In doing so, Nadler joined 17 other retiring members of the U.S. Congress who have so far endorsed candidates in primary elections to succeed them.

Four of the eight U.S. senators (50%) who are not seeking re-election this year have endorsed a candidate in the respective primaries to succeed them. Two of those endorsed candidates are Democrats, and two are Republicans.

All four of those endorsed candidates are running in contested primaries.
